rom laboratory studies of Martian meteorites and analyses of rocks on the planet's surface. (It will be some time before we can actually bring rocks back from Mars.) The Mars Pathfinder, lowered onto the surface in 1997, supplied a wealth of information about the red planet. The orbiting Mars Global Surveyor, which completed its main work on January 31, 2000, has relayed more data about Mars than all of the previous missions combined. McSween will also discuss future Mars spacecraft missions and what new information they will provide.

NORTH CAROLINA GROUNDWATER ISSUES
(Friday, April 6, 8:15 a.m. 12:00 p.m., Hannover Ballroom I)

Demand for groundwater in North Carolina is expected to increase over the next several years because of significant population, industrial, and agricultural growth. In a session titled, "Groundwater Conditions in Coastal Aquifer Systems: Past, Present, and Future," scientists will discuss issues affecting North Carolina's groundwater supply. Highlights include:

The Position of the Fresh Water-Saltwater Interface in Aquifers Underlying Six Counties in Northeastern North Carolina
Michelle L. Volosin, Dept. of Geology, East Carolina University, Greenville, NC, mlv0429@mail.ecu.edu, 252-328-1364, and Richard K. Spruill, Dept. of Geology, East Carolina University, Greenville, NC, spruillr@mail.ecu.edu, 252-328-4399
An essential part of assessing the water resources in this region involves understanding the physical and chemical characteristics of the underlying aquifers. This talk is focused on area sources of groundwater and important factors in sizing them.
